Instead of indicator circles, we use colors and bold text.
The icon turns a doubly-saturated indicator color,
and the accompanying text (if any) turns bold.
In my limited testing, this works out very nicely aesthetically.
And it's much more lightweight!

ChangeLog: Changed
Acrylic is defined as having a background
similar to panel + transparency and backdrop.
Simply change everything that is _acrylic to be _panel instead.
